最大边线噪声级算法研究

Study of maximum lateral noise level arithmetic

在新飞机适航审定过程中,噪声适航是非常重要的一环。而在噪声适航审定过程中,边线噪声级又是特别难以确定的。基于此,依据有效感觉噪声级和飞行高度之间的函数关系探讨了一种计算最大边线噪声级的算法,为噪声适航审定提供了可供借鉴的计算方法。

During the certification of new aircraft, noise certification is a very important process. The lateral noise lever is hard to decide during the process of noise certification. Based on the difficulty, the paper study out a method of calculating the maximum lateral noise lever based on the function of EPNL and the flight altitude. So it can provide the effective method of noise certification.
